Summary

Late corticosteroid treatment may improve outcomes for bacterial meningitis patients with parainfectious vasculitis. Cerebrospinal fluid matrix metalloproteinase-9 (MMP-9) levels may indicate this serious complication.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Immunology

Background:

  • Bacterial meningitis presents significant mortality and neurological sequelae risks.
  • Parainfectious vasculitis is a recognized complication leading to ischemic brain damage, yet treatment remains unclear.

Observation:

  • A 53-year-old male with pneumococcal meningitis developed extensive ischemic lesions in the brainstem and basal ganglia due to vasculitis.
  • Clinical and radiological improvements were noted following delayed corticosteroid administration.
  • Vasculitis recurred upon steroid cessation, stabilizing with immunosuppressive therapy reintroduction.

Findings:

  • High cerebrospinal fluid (CSF) matrix metalloproteinase-9 (MMP-9) levels correlated with symptomatic vasculitis.
  • MMP-9 levels decreased significantly with corticotherapy and vasculitic symptom regression.

  • No correlation was found between CSF MMP-9 levels and white blood cell counts.

    • Implications:

    • Late corticosteroid therapy can be effective for parainfectious vasculitis in bacterial meningitis.
    • CSF MMP-9 may serve as a valuable biomarker for detecting vasculitic complications in bacterial meningitis.
